The 1st EVER and MOST ADVANCED Ophthalmological Calculator for iPhone/iPad just got better! A must-have tool for all Ophthalmologists.

NEW! - EB TORIC:
• Fastest and safest Toric IOL "MARKING" SYSTEM on the market! Just take a photo of the patient's eye and the internal gyroscope and code will do the rest.
• Say goodbye to manual marking in sitting position and corneal abrasions!
• Save yourself thousands of dollars: no need for expensive and cumbersome external hardware which takes long time to register the eye and sometimes will leave you with failed registration and no reference at all for toric IOL alignment..
• Watch the video! Torchlight just added.

NEW! - BORASIO TORIC IOL CALCULATOR:
• Option for Posterior Corneal Astigmatism now available
• Naeser / Savini Optimized Keratometric Astigmatism formula (officially approved by its Authors)
• Very accurate SIA vector calculations
• Various options for Toric IOL power conversion at the IOL plane: FULLY AUTOMATIC / Vergence Formula (option of custom ELP) / Toricity ratio (option of custom ratio) / Han Bor Fam meridional analysis.
• Full integration with EB Toric: Toric IOL Axis and the Incision location are automatically fed to EB Toric for intraoperative IOL alignment.
• Full integration with the other calculators within the app (all calculators can feed data directly to EB Toric IOL Calculator). This is especially useful for post laser refractive surgery eyes where different formulas are needed.

NEW! - Rx BEAM:
• Send prescriptions to your patients in a flash by means of QR codes!
• Patients scans the QR codes and the medication dosage, frequency and duration is automatically added to their calendars!!

CATARACT SURGERY OUTCOMES CALCULATOR - GROUP ANALYSIS:
• Refractive outcomes calculator (mean biometry error and SD)
• A Constant Customization with optional upgrade. Discover your own custom A constant and achieve better results!

BIOMETRY POST LASER REFRACTIVE SURGERY:
• BESSt 2 and BESSt 1 (Pentacam® required)
• BMR/BHR: Borasio IOLMaster® Myopic/Hyperopic Regression (the latest and unpublished post laser refractive surgery formula. No need of any preoperative data! Works also with other biometeres).
• Double K adjustment for SRK/T, Hoffer Q, BESSt 1 (for geeks)

SIA CALCULATOR AND PLOTTER FOR GROUPS OF EYES (AstigPLOT):
• Make amazing high res, publication-level, astigmatism PLOTS for Congress presentations and Scientific Paper Submissions.
• Calculates the Group's ARITHMETIC and VECTOR Mean Astigmatism and Mean SIA (+/- SD)
• Double-angle polar plots are AUTOSCALING to the max value in the series and can be rescaled with a click. CENTROIDS are shown.
• Plots can be sent by email. Email includes a csv file with all the individual SIA results

SIA CALCULATOR FOR SINGLE CASES (AstigMaster):
• Calculates Vector Surgically Induced Astigmatism (SIA) using K values or Refractions
• Also shows cartesian (X;Y) conversion of each SIA vector

STANDARD BIOMETRY:
• SRK/T, Hoffer Q formula (officially approved by their Authors)

ASTIGMATISM CORRECTION REDUCTION CALCULATOR:
• Predicts the final astigmatism following incision misplacement or Toric IOL misalignment

VISUAL ACUITY CONVERTER:
• Converts VA between LogMar, Snellen and Decimal notations

CORNEAL-SPECTACLE PLANE CONVERTER:
• Converts Refraction between Corneal and Spectacle Plane for a given back-vertex-distance (BVD)

CARTESIAN-POLAR NOTATION CONVERTER:
• Converts Astigmatism from Polar (eg +3.25x30) to Cartesian Notation (eg X=1.63; Y=2.81). Essential when computing averages of refractions and for statistical analysis.

OPTICAL FORMULAS:
• Thick Lens Equation (Gaussian Optics)
• Thin Lens Equation (converts Ant r to corneal power and viceversa)
• Custom Keratometric Index-based calculations (converts Ant r to Corneal Power using custom KI)

• Phaco Outcomes Calculator (mean biometry error and SD)
• A Constant Customization optional upgrade (to discover your own custom A constant and achieve better outcomes)

BIOMETRY POST LASER REFRACTIVE SURGERY:
• BESSt 2 and BESSt 1 (Pentacam® required)
• BMR/BHR: Borasio IOLMaster® Myopic/Hyperopic Regression (the latest - unpublished - post laser refractive surgery formula - No need of any preop data! Works also with other biometeres).
• Double K adjustment for SRK/T, Hoffer Q, BESSt 1 (for the geeks)

SIA CALCULATOR AND PLOTTER FOR GROUPS OF EYES (AstigPLOT):
• Make amazing high res, publication-level, astigmatism PLOTS for Congress presentations and Scientific Paper Submissions.
• Calculates the Group's ARITHMETIC and VECTOR Mean Astigmatism and Mean SIA (+/- SD)
• Double-angle polar plots are AUTOSCALING to the max value in the series and can be rescaled with a click. CENTROIDS are shown.
• Plots can be sent by email. Email includes a csv file with all the individual SIA results

SIA CALCULATOR FOR SINGLE CASES (AstigMaster):
• Calculates Vector Surgically Induced Astigmatism (SIA) using K values or Refractions
• Also shows cartesian (X;Y) conversion of each SIA vector

ASTIGMATISM CORRECTION REDUCTION CALCULATOR:
• Predicts the final astigmatism following incision misplacement or Toric IOL misalignment

VISUAL ACUITY CONVERTER:
• Converts VA between LogMar, Snellen and Decimal notations

CORNEAL-SPECTACLE PLANE CONVERTER:
• Converts Refraction between Corneal and Spectacle Plane for a given back-vertex-distance (BVD)

CARTESIAN-POLAR NOTATION CONVERTER:
• Converts Astigmatism from Polar (eg +3.25x30) to Cartesian Notation (eg X=1.63; Y=2.81). Essential when computing averages of refractions and for statistical analysis.

OPTICAL FORMULAS:
• Thick Lens Equation (Gaussian Optics)
• Thin Lens Equation (converts Ant r to corneal power and viceversa)
• Custom Keratometric Index-based calculations (converts Ant r to Corneal Power using custom KI)
